      Abstract: With the advance of smart power grid construction,the terminal laying rate of intelligent acquisition

equipment has been greatly improved,and the demand-side terminal electrification has become an irreversible trend.In recent years,the problems of users' default power supply and private overlapped lines in low-voltage distribution system frequently appear. The emergence of these problems not only affects the safe operation of the distribution network,but also affects the operation risks of power supply enterprises. It is urgent to explore the real-time modeling technology of the distribution network to accurately identify the access information of users and ensure the safe and stable operation of the distribution network. Firstly,the technical situation of distribution network was analyzed from three aspects:structure characteristics,power supply mode and information integration technology of distribution network model. On this basis,the research status of the key issues of distribution network real-time modeling was summarized from the physical topology analysis,topology identification and topology key verification technologies.Furthermore,the possible future research directions were prospected based on the key technologies of distribution network real-time modeling,in order to provide reference for future research.


      Key words: distribution network;real-time modeling technique;topology identification;reactive power
